Saturday 15th September was Open Day for the YHA Hostel at Idwal Cottage on the A5 near Llŷn Ogwen at the head of the Nant Ffrancon Valley
In Wales, by Easter 1931, four hostels were open with 130 beds.
One of these first four hostels was Idwal cottage, 1000ft above sea level at the head of the Nant Ffrancon, a site of sombre and a magnificent loneliness. Mr Symonds contacted Lord Penrhyn, its owner, asking if the Y.H.A. could use it. The latter agreed and generously let it to the Merseyside Group at a low rent. It is still one of the most popular hostels in the country, turning away thousands every week in August and September, holding records for over-nights; 4,653 were registered in 1932."
